IMPROVEMENT EN' PRESERVING MEAT.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit may concemr.-

Be it known that I, WILHELM WIESMANN, of Bonn, in Prussia, have invented a new and useful Improvement in Preserving Meat; and I do hereby declare the following to be 'a full, clear, and exact description thereof, which will enable those skilled in the ait to .meat is protected against the influence of-the atmosphere, and,"by the charcoal, all the air, contained between the layers, and all the gasesemanating from the meat, and capable of predisposing decomposition, are absorbed, and the meat can be preserved for a long time.

The vessel in which the meat is put up contains a v series'of horizontal perforated partitions, and its top is provided with an oil-space, whereby the same can be hermetieallyclosed against the access of the ritmospheric air.`

In-carrying out my invention, I separate the meat carefully from 'all the bones, wash it, and wipe and press it in linen cloth, until all the blood and moisture have disappeared.

Whenv it is desired to preserve the meat for more l than two months, I heat the meat in a suitable apparatus by the action of steam, for the purpose of coagulating the albumiuous substances; but this heatingprocess can -be dispensed with if the, meat is to be preserved for less than two months.

After the-pieces of meat have been prepared, as

. Y above described, I splinkle them with pulverizcd saltu ptetre, in the proportion, one part, by weight, of saltpetre, to three hundred. parts of meat, and then I coa-t Y -,them with a layer'of olive-oil, applied by a brush or in any other suitable manner.

` After each piece of meat has thus been carefully covered with saltpetre and a coat of olive-oil, I place the saruelinto a-suitable vessel, in which the same are 'compressed-in layers of about six inches depth, and betweenthese layers' of ineat I introduce layers .of animal-charcoal, formed by filling said charcoal, in a granulated state, into coarse linen bags, in the proportion'of about one part, by weight, of coal, tol eight parts of meat, each bag being made to contain about three ounces of coal, while a small quantity of the c oal is reserved for the purpose of filling up the interstices remaining between the adjacent bags.

By the charcoal, the air contained in the receivingvessel is absorbed, and also the gases emanating from the meat, and liable to cause or'promote decomposition.

The Vessel A i Wlihplathe'meat is; by prefer.. ence, made in the formof trund mue, otinned Y, c

or enamelled sheet-iron, rf-an'yother suitable material. In the .interiorfaof Iiis'vessel is placed aseries a, which are supported by of perforated diaphragm angular lugs attached, at suitable distances apart, to

the interior of said vessel. ,On the diaph lagnisior shelves is plaeeda layer of bags filled with charcoah then a layer of meat, and vs o on, until the vessel' is filled, ca're being taken to have a layer of charcoal-bags on the top.

The vessel A is closedby a lid, c, which is j' to a flange, b, on the edgeofthe vessel. Between thei f lid and thc flange a disk, e, of sheet-metal,l isintro-v duced, and the joints between this disk and the flange b and the lid c are rendered tightgby packing-rings g d, of card-board steeped in tallow or any other suitable material. v v From the disk e rise projections, j, whichserveto support the lid c.

Thelid c is provided with .a,stop-cock,'h, which is secured' in the hemispherical cap j, and with another`L stop cock, t, which is secureddirectly in the lid. Each of these cocks is provided with a cup-shaped mouthpiece, and the mouth-piece of the cock .i is about on af level with the top of the cap, j. Through the cock h I 'the lid c and disk e, and as soon as the oil rises into.'rv veinouth-j-V piece of the cock i, both cocks .are closed. ""*Bygthe layer olive-oil is introduced into the space-below? of oil thus formed on the top of the disk e, the access of air to the interior of the vessel A is eii'ectually prevented. f

'Having thus described my invention',-

What I claim as new, and desire to secure by Let- 1. The within-described process of preserving-great, by first coating the pieces' of meat with powdered; saltpetre and olive-oil, and then storing them away in a hermetically-closedvessel, with intermediate layers' 1 l* of charcoal filled in bags, as herein set forth.

2. Thevessel A, provided with perforated movableshelves a, and closed bya disk, e, and llidkc, leaving ang:-

'oil-space, which is filled through stop-cocks 7m'. all as shown and described.
